Creating a Level 7 interrupt file for UAE

[redblade]

Hi

How would I got about doing this?

I've opened up AR3.rom and it seems to be 'NuNuAction..'

So where about's do we put the start code of the tool in the level7 rom file?

Also how hard would it be to modify PDX-ARIV to a Level7 rom file??

You can't just trigger level 7 IRQ and expect it to work. AR cartridges have hardware logic that must be also emulated (for example two first bytes contain status io bits and other stuff, they are not mapped to rom space).

Anyway, map the rom at address 0 and you'll find level 7 IRQ autovector points to correct address automagically

Okay, I understand the first paragraph.

The second paragraph ?!?!? You want me to do a hex dump from $000 to find the level 7IRQ autovector points? Which point to some memory address (the start code) located in the AR3.rom file?.

Also does WinUAE do a checksum check on the AR3 roms before running it ?
